Round Robin Calculator
Add your picks, choose the parlay size and see every combination, the total cost and the payout if they all win.
How a round robin works
Each combination is a normal parlay: multiply its legs' decimal odds and the stake. Four picks by 2s gives six parlays, so a 10 stake on each costs 60.
If every pick wins, all six pay. If one loses, the three parlays that include it lose and the other three still pay. You need at least as many winners as the parlay size to get anything back.
FAQ
What is a round robin?
A round robin turns a list of picks into every possible smaller parlay. Four picks by 2s makes six 2-leg parlays, so you can still get paid when some picks lose.
How many parlays are in a round robin?
It is the number of ways to choose the parlay size from your picks: 4 picks by 2s is 6 parlays, 5 picks by 3s is 10, 6 picks by 2s is 15.
Is a round robin cheaper than a parlay?
No. You stake every parlay separately, so the total cost is the stake times the number of parlays. The trade-off is a smaller top payout for more ways to win.
